NOV. J. AMADOR NAP RAISING ATTACHMENT FOR CLEANING DEVICES Filed Oct.27. 1960 2 Sheets-Sheet 2 r f f INVENTolc JOAN AMADOR United StatesPatent-IAO 3,065,491 NAP RAISING ATTACHMENT FOR CLEANING DEVICES y JoanAmador, 28 Pascack Road, Hillsdale, NJ. Filed Gct. 27, 1960, Ser. No.65,507 2 Claims. (Cl. 15-396) This invention concerns a nap raisingattachment for vacuum cleaning devices or the like.

According 'to the invention there is provided an elongated hollow memberor body which is mountable to a iloor cleaning device of a vacuumcleaner. The member has an outer wall with a plurality of integrallyformed flexible iingers which can be drawn through the nap of a carpetor rug to raise the nap, restoring its resiliency, improving itsappearance, and rendering it more easily cleanable by the vacuumcleaner. The outer wall of the hollow member is formed with elongatedslots or openings through which air enters the body under suctiondrawing dust and debris from the rug or carpet being cleaned.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a perspective view of a vacuum cleaning device with anattachment embodying a modification of the invention mounted thereon.

FIG. 2 is a top plan view of the attachment per se.

FIG. 3 is a bottom plan view of the attachment.

FIG. 4 is a sectional view taken on line `4 4- of FIG. 2.

FIG. 5 is a sectional view taken on line 5--5 of FIG. 2.

FIG. 6 is an end elevational view of another attachment.

FIG. 7 is a top plan view of the preferred attachment embodying theinvention.

FIG. 8 is a sectional View taken on line `8 8 of FIG. 7.

FIG. 9 is an exploded perspective view on a reduced scale of componentsof the attachment of FIGS. 7 and 8.

FIG. 10 is a perspective view of a Valve element employed in theattachment of FIGS. 8 and 9.

FIG. 1l is a perspective view of a nap raising device shown in use on acarpet o1' rug.

FIG. l2 is a sectional view on an enlarged scale of the device of FIG.l1.

Referring to FIGS. 1-5, there is shown a device 20 including anelongated generally rectangular body 21 preferably formed of moldedrubber. The body has llat parallel outer walls 22, 24 and narrow sidewalls 26. The upper, outer `wall 22 is formed with an elongated centralopening 28 which may be disposed in registration with a similar opening30l -in the head 32 of a conventional Vacuum cleaning device 33, such asgenerally used for cleaning floors. A vacuum hose 34 is attached to apipe 36 secured to a socket 37 on head 32 as shown in FIG. l. The head32 is elongated in form and is engaged by elastic bands or straps 38secured in brackets 41 by pins 42. The brackets are formed in pairs onthe upper wall 22 and spaced apart. The straps securely engage the endsof head 32.

The underside or lower wall 24 of the body 21 is formed with a pluralityof slotted openings 43. When the device 20 is drawn over a 'rug orcarpet in the manner of a rake or comb, the ngers 35 disturb the nap orpile thereon and an air stream drawn through the slotted openings 43sucks the nap or pile upwardly thereby raising the same, and at the sametime sucks any dust that might be in the rug or carpet.

3,065,491 Patented Nov. 27, 1962 ICC In the attachment 20a of FIGS. 7and 8, the upper wall 22a is a removable plate secured by screws 23inserted through holes 29 to the elongated rectangular body 21a. Body21a is preferably formed of rubber or flexible plastic material such aspolyethylene or vinyl and has integrally formed flexible lingers 35a onits underside or lower wall 24a. Slotted openings 43a in the Wall 24'pass air and dust therethrough. Slot 28a in plate 229' may be placed inregistration with opening 30 of head 32 of the vacuum cleaner device ofFIG. 1. `Brackets 4la are secured to generally rectangular plates 47shown to best advantage in FIG. 10. These plates of which two areprovided slide in the space dened between Walls 22a and 24a. Elasticstraps 3Sa are secured to the brackets by pins 42a. The brackets move incutouts 45 formed at the edges of wall 22a and are guided between theedges of the cutouts and the adjacent side walls 26a of the body 21a. Bygrasping the straps and moving the plates toward and away from eachother the size of the opening defined between edges Vof the plates `47is adjusted. This regulates -the size of opening through wall 22H atslot 28a through which the air stream passes and thus controls the speedand force of the suction applied to the rug or carpet being treated. Thestraps 38a mount the attachment on the head of the vacuum cleaningdevice in the same manner as illustrated in F-IG. 1.

The straps 38 and 38a may be made of rubber. If desired the straps maybe formed as elastic coil springs as shown by springs 50 in FIG. 6.These springs have coiled ends 5K1 engaging the pins 42 in brackets 41.Other parts of the attachment 20b correspond to the structure ofattachment 20, and are identically numbered.

In FIGS. 1l and l2 is shown a nap raising device 20 provided with aninterchangeable handle 36. The handle 36 has a threaded bottom end 72adapted to be threaded into a threaded socket opening 74 formed in thetop surface of the body 26 of the device 20. The body has a at outerwall 467 with flexible fingers 35'. The device 20 raises the nap of therug to enhance its appearance and to restore its resiliency. In otherrespects this form of the invention is similar to the previous form andthe corresponding parts may be recognized by the same reference numeralswith a prime added.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and that various changes andmodifications may be made within the scope of the invention as definedin the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:

1. A device for raising the nap of a rug or the like, comprising anelongated hollow body with flat spaced upper and lower walls, said upperwall having an opening adapted for placement in communication with anopening in a vacuum cleaner head, said lower Wall having a plurality ofopenings adapted -to pass an air stream therethrough, a plurality ofspaced exible ngers extending from said lower wall for combing andraising the nap of the rug while the rug is being cleaned by the vacuumcleaner, and a pair of generally rectangular plates slidably disposed insaid body between said walls for adjusting the size of said opening toregulate the air stream passing through the body, said upper wall beinga plate removably secured on the body, said upper wall having recessesat opposite edges thereof, said plates carrying spaced bracketsextending through said recesses, with 4ends of flexible straps secured-in said brackets for attaching said body to said head.

2. A device for raising the nap of a rug or the like,

comprising an elongated hollow body with Hat spaced 'upper and lowerwalls, said upper wall having an opening adapted for placement incommunication with an opening in a vacuum cleaner head, said lower wallhaving a plurality of openings adapted to pass an air streamtherethrough, a plurality of spaced eXible ngers extending from saidlower Iwall for combing and raising the nap of the rug While the rug isbeing cleaned by the vacuum cleaner, and a pair of generally rectangularplates slidably disposed in said body between said walls for adjustingthe size of said opening to regulate the air stream passing through thebody, said upper wall being a plate removably secured on the body, saidupper wall having recesses at opposite edges thereof, said platescarrying spaced brackets extending through 'said recesses, with ends offlexible straps secured i'n said brackets for attaching said body tosaid head, said ngers being integrally formed with said lower wall ofthe body, the uopenings in said lower wall being elongated slots.
